The basic steps of this method are as follows.The firststep is to derive a necessary condition such that the families of quasipolynomials withone parameter,corresponding to the edges of the polytope,have pure imaginary rootsby using the Dixon's resultant for polynomials.Then to check that the casescorresponding to the parameters obtained in the first step are in fact impossible byusing the generalized Sturm criterion and some stability criteria.

其基本思路是先利用多项式方程组的Dixon结式理论导出使各棱边对应的单参数特征拟多项式有纯虚根时，参数值应满足的一个等式条件，即所谓的Dixon结式等于零，然后由广义Sturm判别法验证对所有参数值，Dixon结式不等于零，或使结式等于零的解不产生特征拟多项式的纯虚根。

Qi Niandian Wugufengdeng prayer is the emperor of the premises, is a three Zhongyan Basilica of the round, 38 meters high, 32.72 meters in diameter, blue glazed tile roof, brick-wide, not long PURLIN beams, depends entirely on 28 and 36 pins Fang Jue support, in the form of construction on a high artistic value.

基于在磷酸溶液中，亚硝酸根对溴酸钾氧化邻苯二酚紫的褪色反应具有催化作用，建立了催化光度法测定微量亚硝酸根的新方法。

May 3. I began with my Saw, and cut a Piece of a Beam thro', which I thought held some of the upper Part or Quarter-Deck together, and when I had cut it thro', I clear'd away the Sand as well as I could from the Side which lay highest; but the Tide coming' in, I was oblig'd to give over for that Time.

五月三日我动手用锯子锯断了一根船梁。我猜想，这根船梁是支撑上面的甲板或后面的甲板的。船梁锯断后，我尽力清除旁边积得很高的泥沙。但不久潮水开始上涨，我不得不暂时放弃这一工作。

Existing literature on the inquiry,collation and analysis,this article had the following major tasks:1st,finite element simulation of the current analytical methods are summarized,and system introduction finite element software ADINA and ANSYS applied in the reinforced concrete built-up section.2nd,system introduction reinforced concrete component material performance as well as reinforced concrete nonlinear analysis main mathematical model. 3rd,the use of ANSYS and ADINA software simply supported beam simulation were compared.4th,uses the ANSYS analysis software,conducted 7 radical center bearing reinforcing steel-side steel pipe concrete short stump simulation test research,the research had indicated the reinforcing steel the existence strengthened the pillar ductility greatly.5th,based on ANSYS,has conducted 2 radical center bearing reinforcing steel-side steel pipe concrete member in bending simulation test research.
